Insulin therapy helps to control diabetes, but a better understanding of the disease could spare diabetics a lot of pain. Robert Kennedy, a professor of chemistry at the University of Florida in Gainesville, has investigated insulin-secreting cells using Zinquin, a fluorescent zinc dye. In normal pancreatic beta cells, when glucose enters a cell it causes the secretion of an insulin-zinc complex. He put the zinc dye in anionic form around the beta cells to image and measure the release of insulin. Robert Kennedy bathed pancreatic beta cells in FluoZin-3, and continuously scanned...Read full article
